The paraboloid z = 3 − x − x2 − 2y2 intersects the plane x = 1 in a parabola. Find parametric equations in terms of t for the tangent line to this parabola at the point (1, 3, −17). (Enter your answer as a comma-separated list of equations. Let x, y, and z be in terms of t.
Answer:
the required parametric equation is:
x = 1
y = t + 3
z = -12t - 17
Step-by-step explanation:
From the given information:
We are to express x,y, and z in terms of t.
The purpose of this question is to find the parametric equations in terms of t.
Given that the tangent line related to the parabola is the point (1,3, -17)
Provided that the paraboloid z = 3 - x - x² - 2y² intersect the plane x = 1 in a paraboloid; then:
z = 3 - 1 - (1)² - 2y²
z = 1 - 2y²
Suppose y = t, then the parametrization is given by:
(x (t), y(t), z(t) ) = (1, t, 1 - 2t²)
(x' (t), y'(t), z'(t) ) = (0,1, -4t)
At the point (x,y,z) = (1,3, -17)
For t (=y) = 3
Hence, (x'(3),y'(3),z'(3)) = (0,1, -12)
Therefore, the equation of the tangent line can be expressed as:
[tex]\dfrac{x-1}{0}=\dfrac{y-3}{1}=\dfrac{z-(-17)}{-12}=(t)[/tex]
x - 1 = 0, y -3 = t, z + 17 = -12t
x = 1, y = t + 3 , z = -12t - 17
Thus, the required parametric equation is:
x = 1
y = t + 3
z = -12t - 17

Which one and don’t lie!!
Answer:
I am 99.99% sure its D.
Step-by-step explanation:
That red line is on the negative side of the x-axis and since all the numbers are 7 I'm just gonna assume that its a negative 7. Good luck sugar plum ;)
Answer: Not lying cause what's the point of lying to someone asking for help. The answer is x = -7
Step-by-step explanation: X= -7 because if you look at a graph with negative and positive on it along with the Y and the X on it. Then you'll see that the middle of the plus is zero the left of the middle (going down the X axis) is negative. And the right side of the X axis is positive and the line is on the negative side of the X axis. That's why instead of it being Y= -7 ( which is NOT the answer) is wrong because the line is over the X axis instead of the Y axis.

"George earns $9.50 per hour and $35.00 commission per sale, but he pays $12.00 in license fees each week. Mary earns $13.50 per hour and $11.25 for every defect she corrects, but she must pay $37.00 for tool rentals each week. The expressions below represent their individual earnings for every two-week pay period. George: 9.5h+35s−2(12) Mary: 13.5h+11.25d−2(37) where: h = the number of hours worked s = the number of sales George makes d = the number of defects Mary corrects if George and mary work the same hour each period, which expression represents their combined earning for one day earning period"
given
week pay period.
George: 9.5h+35s−2(12)
Mary: 13.5h+11.25d−2(37)
their combined earning is the sum of the individual earning
9.5h+35s−24
+13.5h+11.25d-74
23h+35s+11.25d-98
The expression is 23h+35s+11.25d-98
2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?
Answer:
He can buy 5
Step-by-step explanation:
To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.
Hope this helps :)
Step-by-step explanation:
One action figure can be shown as x so x=$3.50.
Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.
20÷3.50 =5 2.5/3.5
So x=5 2.5/3.5

Using the approximation 3.14 for pi, what is the radius of a circle with circumference 69.1 m?
Answer:
11.0
Step-by-step explanation:
Circumfrence = 2 x pi x r.
making radius, r the subject of relation, you.get 11.003184713
Answer:
Hey!
Your answer is 11cm!
Step-by-step explanation:
So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14
Radius = [tex]\frac{C}{2\pi }[/tex] ... (that's the formula)
WE SUBSTITUTE IN:
Radius = 69.1/2 x 3.14
69.1/6.28
This equals = 10.99760656765
BUT 11cm when you round it to the next whole number or 2sf

Read the passage. Which statement best describes how Belle changes over the course of the story?
Riding a Bicycle
It was a bright Sunday morning when Belle woke up with the biggest smile on her face. She had been looking forward to this day for a long time. Her father was going to teach her to ride a bicycle. She dressed quickly and gulped down her breakfast.
After breakfast, Belle’s father showed her the different parts of a bike. Then he said he would hold onto the back of the bike while she peddled. But Belle’s excitement got the better of her. She said she wanted to try riding by herself. Her father let go. Belle quickly lost her balance and crashed to the ground. The fall dazed her. She grumpily agreed to let her father keep holding the bike while she rode.
Every once in a while, he would let go. The moment he did, Belle would lose her balance and topple over. Her father explained that this was perfectly normal. He said that all first-time riders fall. Even so, Belle’s mood darkened with each fall. After a while, she wanted to give up and return home.
Belle’s father tried to talk her out of quitting. He pointed toward some other children biking nearby. He showed her how happy they looked as they rode their bicycles. He told her she needed to keep trying. With a little more effort, she would soon enjoy riding just like the other children. His words gave Belle the determination to keep going.
After several more failed tries, Belle finally got the hang of it. She began gently peddling by herself, beaming with pride. She had finally done it! That night, she went to bed with a couple of bruises and cuts. But she had an even bigger smile on her face than she’d had in the morning. She would forever remember this day and the lesson she learned about never quitting.
A.
Belle starts showing more trust in her father as he teaches her how to ride a bike.
B.
Belle becomes less excited as the story goes on, until her excitement for bike riding disappears.
C.
Belle learns both how to ride a bike and how important it is not to give up.
D.
Belle gets hurt from falling off her bike, which scares her away from bike riding for good.

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −190 feet. Then she continued to hike down for another 20 minutes at a different rate. Her change in elevation for this part of the hike was −200 feet. During which portion of the hike was her rate of change in elevation greater? Complete the explanation. Her rate was faster in the (Select: First, Second) part of the hike, because her heart rate was ____ ft/min in the first part and ___ ft/min in the second part.
Answer:
Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part
Step-by-step explanation:
Portion 1
Time taken to hike down = 10 minutes
Change in elevation = - 190 ft
Portion 2
Hiked down for further 20 minutes
Change in elevation = - 200ft
During which portion of the hike was her rate of change in elevation greater?
Rate of change in elevation :
Change in elevation / time
Portion 1:
Rate of change in elevation :
Change in elevation / time
- 190 ft / 10 minutes = - 19 ft/minutes
Portion 2:
Rate of change in elevation :
Change in elevation / time
- 200 ft / 20 minutes = - 10 ft/minutes
Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part
